1432-0033: new campaign target

  copy of [vsnet-alert 5037, T. Vanmunster]:

Dear colleagues,

I'm observing the dwarf nova 1432-0033 in response to the recent =
outburst reported by R. Stubbings (VSNET-ALERT 5030), using the 0.35-m =
f/6.3 telescope with unfiltered ST-7 CCD of CBA Belgium Observatory. =
Also running my "real-time" light curve generator, allowing on-the-fly =
CCD data reduction and light curve visualisation.

The light curve clearly shows a superhump-like profile with an amplitude =
of about 0.6 mag. It's very difficult to determine the period of the =
signal (given the noise due to the low altitude of the object). A guess, =
looking at the light curve on screen, yields a value of approx. 0.07 d.

In Astrophys. J. Sup. 78, 409, 1992, Berg et al. mentioned this object =
as an emission-line CV, with a "resemblance to HT Cas and U Gem".   The =
object is located at 14h32m25.88s, -00d33'00".9 (J2000), with a reported =
quiescent magnitude of 18.5

I'll continue monitoring this object as long as possibe (but already =
getting very low now). Assistance from other observatories would be =
appreciated.

Best regards,
Tonny

    The object is naturally brought to the VSNET campaign program!  Please
continue to keep a watch!  Judging from the large amplitude of superhumps,
the system might be a (grazing) eclisper.

Regards,
Taichi Kato
